Design of Pressure Actuated Cellular Structures
A novel concept for pressure actuated cellular structures was published by Pagitz et al. 2012 Bioinspir. Biomim. 7. The corresponding mathematical foundation for the simulation and optimization of compliant cellular structures with central cell corner hinges can be found in Pagitz and Hühne 2014 arXiv:1403.2197. The aim of this article is fourfold. First, analytical expressions for optimal mate...
متن کاملShape Optimization of Compliant Pressure Actuated Cellular Structures
Biologically inspired pressure actuated cellular structures can alter their shape through pressure variations. Previous work introduced a computational framework for pressure actuated cellular structures that is limited to two cell rows and central cell corner hinges. This article rigorously extends these results by taking into account an arbitrary number of cell rows, a more complicated cell k...
متن کاملUnder-Actuated Kinematic Structures For Miniature Climbing Robots
This paper presents two biped designs for miniature climbing robots. The designs use underactuation to satisfy space and weight constraints. In the first design, one actuator provides steering and another two propel the robot in a cartwheel style gait. The cartwheel gait is quite effective but space required for the maneuver precludes certain applications. The limitation is overcome in the seco...
متن کاملA Novel Actuated Composite Tape-spring for Deployable Structures
This paper presents a novel composite tape-spring that is suitable for use as a structural element of deployable space structures. The tape-spring uses a combination of material orthotropy and prestress to achieve the unique property known as neutral stability. A consequence of this property is that the tape-springs can be partially rolled and they neither want to unroll or rollup. Previously i...
متن کاملExtraction of Coherent Structures from Natural and Actuated Flows
We present feature-extraction techniques for numerical and experimental data of complex fluid flows. Focus is placed on efficient analysis and visualization of coherent structures of snapshots, temporal evolution and parameter-dependency of coherent structures. One key enabler are Galilean invariant flow quantities based on pressure, acceleration, vorticity and velocity Jacobians. Other importa...
